I am putting together a server (just a E5200, nothing crazy like an i7) and wanted to know what people usually run for their OS to continue to fold/boinc. I was originally just going to do something like FreeNAS, but I am pretty sure you can't run anything else with that. I have Win7 Pro, XP, Server 2008 (no idea how to use or if it is R2, got from MSDNAA) or would be willing to try a linux distro. Would prefer to avoid WHS, as I would rather spend $100 on another hard drive and deal with what I have available. Won't be any raid (yet) if that makes a difference, just a 24/7 file server for media and documents. Also, it currently only has 1gb memory, but I can probably borrow from a HTPC to make is 2 - 3gb if necessary.
